Fluvia RC3

The Multipurpose Electromagnetic Velocimeter

The FLUVIA electromagnetic velocimeter (or current meter) is a portable device for measuring and recording water flow velocities.

It can also calculate the flow rates thanks to the possibility of entering geometric profiles and gauges of rivers or canals.

Its electromagnetic sensor, with no moving parts, does not retain debris, guaranteeing very high accuracy and reliability. Its hydrodynamic shape associated with a reduced size allows its use even with minimal water and flow.


Temporary and fast measurements of velocities and flows for many applications in fresh water, salt water, wastewater...:

  • Rivers and streams
  • Irrigation canals
  • Inlet canals
  • Sewerage networks
  • All open channel gauging

Main benefits

  • The measurement is not dependent on water turbidity, temperature, conductivity (except for extreme values).
  • The measurement is unaffected by turbulence, vibrations, external noise, etc.
  • Suitable for clean and wastewater
  • Can operate with low water levels and low velocities
  • Fast and accurate measurements, without the need for special analyses and processing
  • Bidirectional measurement
  • Robustness (no moving parts, no transducers, etc.)
  • Allows you to enter the profiles of canals or rivers to directly calculate the flow rate.
  • Recording of measurements and profiles
  • Easy to use, with a large graphic touch screen and navigation wheel for the configuration and display of instantaneous and recorded measurements (curves)
  • Possibility of adding sensors, including water level sensor (options)
  • GPS location, Bluetooth communication, Cellular communication (options)
